How to Design a Porch Addition

Many homeowners that are looking to extend their outdoor living space often consider a porch addition. Porch additions are a way to extend the living space of a home without having to do extensive remodelling of the walls and roof lines. Front porches are attractive to homeowners because of the added use and the option of being able to do the work themselves without having to hire a professional.

  1. 1

    Determine the best location in your house where you can place the porch addition. One of the most common locations is to extend the front entry.

  2. 2

    Measure the location of the front porch area with a measuring tape. It is also a good idea to measure the entire perimeter of your house. This will help you to see if the porch addition is proportional to the rest of the house.

  3. 3

    Draw the outline of your house on a piece of paper based on the measurement you took. It is best to draw the house to a scale using an architectural scale as your guide. A typical home floor plan is draw at 1/4-inch per foot.

  4. 4

    Design how the front porch addition will look. Look at different design magazines and books to see what styles you like. Drive around your neighbourhood and see what other people have done and if it would work with the style of your home.

  5. 5

    Determine if you want an enclosed porch or open porch design. This can be dependent on the location of the porch. If you are in the southwest climates, you might want to consider an open porch design to enjoy summer breezes. If you are in colder climates, you might want to consider an enclosed porch design, as this will help to insulate the home during the cold winter months.

  6. 6

    Draw the design of your front porch on the piece of paper where you drew the outline of your home. This will show you how big the porch is in relation to the rest of the house. It will also give you an idea if the location of the porch is right for the layout of your home. A south-facing porch will get a lot of sun and may require a large overhanging roof.

  7. 7

    Draw a rough elevation of the porch to show what the design will look like. The elevation will give you a chance to see if you need to add guardrails, steps, or windows if it's an enclosed porch.
